SPRING-HINGE.

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filedDecember 1, 1919. Serial No. 341,583.

To all whom it may concern:

Be it lmown that LKEMP B. ARTHUR, a citizen .of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Spring-Hinges, of which the following is a specification, reference being had to the accompanying drawms This invention relates to certain improvements in spring hinges, and it is an object of the invention to provide a novel and improved device of this general character whereby the leaves comprised therein may be readily separated without the necessity of disengaging the same from the work, and whereby the hanging or removal of a door or the like is materially facilitated.

It is now the general practice in taking down a door hung by spring hinges to remove the screws or the like coacting with the leaf of each of the hinges. This often results in defacing of the door or frame, and also renders it diflicult to properly rehang the door.

A further object of my present invention is to provide a hinge wherein'these disadvantages are obviated.

'The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved spring hinge whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view in elevation of a spring hinge constructed in accordance with an embodiment of my invention;

Fig. 2 is a sectional view taken substantially on the line 22 of Fig. 1;

Fig. 3 is a sectional view taken substantially on the line 33 of Fig. l, and,

Fig. 4 is a view in top plan of the plate as herein embodied.

As disclosed in the accompanying drawings my improved hinge comprises two sections A and B. Each of said sections in cludes a leaf 1 provided with openings 2 through which anchoring screws or the like are adapted to be inserted to maintain said leaf in applied position. The opposite ends of the leaf are provided with the outstanding flanges 8 substantially at right angles thereto and which have their inner portions extending beyond the inner longitudinal edge of the leaf to provide perforated ears 4. lVhen the sections A and B are assembled the ears 4 of the section B substantially snugly fit between the ears 4 of the section A with the perforations or openings of said ears in register for the insertion therethrough of the removable pintle member P.

The opening or perforation in the lower ear 4 of the leaf B is defined by an upstanding annular flange or. tubular boss 5 through which the pintle member P is also directed.

The annular flange or boss 5 affords a mounting for the lower end portion of a coil spring S. The opposite end portion of the spring S engages or surrounds a boss 6 depending or extending inwardly from a plate 7. The boss 6 is tubular to permit the pintle member P to be inserted'therethrough. The inner end of the bore of the boss 6 communicates with the base of a socket 8 formed in the face of the plate 7. The socket 8 snugly receives a boss or annular flange 9 substantially defining the openingor perforation in the upper ear 4 of the section B of the hinge.

The plate 7 is provided with a tail or extension 10 havingdepending or extending inwardly therefrom a lug 11 with which the upper or adjacent end portion of the spring S engages, said lug being preferably providedwith a groove 12 in which said extremity of the spring seats. The major portion of the plate 7 has its periphery concentric to its axis, and said periphery of the plate 7 is provided with the shoulder 14, which coacts with a lug 15 depending or extending inwardly from the adjacent ear 4 of the section B.

The lower end portion of the spring S or that portion coacting with the flange or boss 5 seats within a groove suitably produced in the adjacent face of the leaf 1 of the section B.

The plate 7 operates to maintain the spring S against displacement between the ears 4 of the section B when the pintle member P is either being removed or ap- I plied, and which maintenance is further assured by the coaction of the shoulder 1A and the lug 15, hereinbefore referred to.

It is also to be understood that the extension or tail 10 contacts with the leaf 1 of the section A whereby the requisite functioning of the spring S is assured to automatically swing a door or the like into closed position.

When it is desired to take down a door or the like, and with which coact hinges constructed in accordance with my invention, it is only necessary to remove the pintle member P of each of the hinges, and the spring S will be retained by the section B. In viewv of this it will be at once seen that with my invention it is not necessary to remove the leaf 1 of either of the sections A or B from applied position, and whereby the defacing of the face of a door or frame is eliminated. With the use of my improved hinge it is also assured that a door can be rehung properly, and which is not always true when the holes in the work in which the anchoring screws extend have been exposed to the elements for any length of time.

From the foregoing description it is thought to be obvious that a spring hinge constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as'limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. A detachable spring hinge comprising, in combination, a pair of leaves each provided with a pair of spaced ears, the ears of one leaf being arranged inwardly of the ears of the second leaf, a pintle member disposed through the ears when the leaves are in assembled relation, the ears of the first-named leaf, said plate having a depending lug with which an extremity of the spring engages, the opposite extremity of the spring having operative engagement with the second leaf, said plate having an extension contacting with the first-named leaf.

2. A detachable spring hinge comprising, in combination, a pair of leaves each provided with a pair of spaced ears, the ears of one leaf being arranged inwardly of the ears of the second leaf, a pintle member disposed through the ears when the leaves are in assembled relation, the ears of the first-named leaf being provided with inwardly directed bosses through which the pintle member also extends, a plate provided with a socket to receive the boss of one of said ears, said plate being provided with an inwardly disposed boss, the pintle member being disposed through said plate and the boss, a coil spring interposed between the ears of the first leaf and having its opposite end portions surrounding the boss of the plate and the boss of the second ear of the firstnamed leaf, said plate having a depending lug with which an extremity of the spring engages the opposite extremity of the spring having engagement with the second leaf, said plate having an extension contacting with the first-named leaf, said plate being provided in its periphery with a shoulder, the adjacent ear of the second leaf being provided with an inwardly directed lug with which said shoulder coacts.

-In testimony whereof I hereunto aflix my signature.

B. ARTHUR.
